Hello I’m swapping my 85 Camaro to a carb but I’d like to keep my electric gauges and from the 92 I took out of and the harness and the 700r4 but I’m curious will the computer even still work with them if the engine isn’t fuel injected anymore

 

The only way you can use 90-92 gauges in a 82-89 car is to swap the entire dah housing. It is NOT a plug-and-play swap,... there will be several changes / modification to the 90-902 dash housing wiring harness so it properly connects to the 82-89 wiring correctly. You will also need to remove the existing dash housing brackets ( spot welded to the firewall ) and install the 90-92 specific brackets. Tranny speedo sending unit will also need to be changed to an electric VSS ( and custom make/install the wiring it needs )

In other words,... you can make it work; but it will take a TON of effort !

 

yea I have the 92 dash and harness I just know the old one ran off the tv cable and I didn’t know if the electric ones would work with a carb

 

No matter what,.... if you swap to a carb ( and do nothing else ) you will need to get yourself a Carb TV cable for the 700R4. The Throttle Body, TPI, V8 Carb, & V6 TV cables are all different lengths and you need to use the right one.



If you expect to try and swap dashes,..... this is what the dash housing bracket look like: ( You'll need to remove the originals and install the 90-92 style. )

82-89:


90-92:




The 82-89 Camaros used a cable VSS in the tranny for speedo,...... the 90-92 cars used and electric VSS. Other than that a 90-92 Camaro tranny is 100% compatible with a 84-89 Camaro.

 

cool thanks I’ll have to get the kit for the tv cable and then for the torque converter bypass do you know when a good time to switch it on is? Would I just switch it on when I’m at a cruising speed?

 

You are going to want to keep using the Torque Converter Lock-Up.
You will overheat and prematurely cause the THM700-R4 unless...
The Transmission is modified (TCC Apply Valve from TransGo), or a Non-Lock-Up TC is used.

The Lock-Up feature is electrically operated and does not require any electronics or computer module.
Vacuum Switch, Brake Pedal Switch, Electric TCC Kits are available to keep Lock-Up.

If you are not savvy with Our Vehicles yet, I recommend the Kit in the Hyperlink below:

Try purchasing this through Summit Racing (or where ever the best deal is):
Product Site

Summit Racing

Also if your Vehicle uses a Speedometer Drive-Cable for the Speedometer/ Odometer...
You will need to obtain an Adapter/ Converter for the Speedometer Gear Housing, to swap to VSS.



Something like the product in the Hyperlink below:
Adapter

 

I am just going back to this comment that you Posted for clarification.

The Interior Wiring for the Instrument Panel is in no way connected to the THM700-R4 Throttle-Valve Cable.
You may be thinking of the Speedometer Drive-Cable for the Speedometer/ Odometer.
The TV Cable must be used, but it only goes to a Carburetor Base-Plate/ Linkage or to Throttle-Body Linkage.

Electric/ VSS Speedometers can be used with any type of Air-Fuel Induction...
The Transmission just needs to have the ability to use a VSS; which the THM700-R4 does.

 

ok cool that’s actually the kit I was getting I just didn’t know if it was a turn it on when the cars on and it does all the work or if you have to switch it on and off while driving

 

My original intention was to go with a tpi with aftermarket heads and the older intake to fit them and just get the manifold and the runners ported but when I sent the computer to get burned the guy said the cam I got is too big so now I’m switching it to carb which I never really wanted to do to begin with

 

You can look into a PROM for the 1990 - 1992 Speed Density/ MAP Induction System and ECM.
That may be an option for you Engine Combination in order to retain TPI.

You would have to search Our Forum for more details/ answers on this...
These Systems were before my time at GM.
The only areas that I did any "Old Technology" research on...
Were Packard Electrical Systems and Hydra-Matic (No Engine or Induction research).
